Problems solved by technology

However, if the control response frame cannot be transmitted at the same data rate as the immediately preceding frame, it must be transmitted at the highest rate in the Basic Service Set (BSS) as specified in the IEEE802.11 standard
Also, unlike legacy format data, HT data has HT preamble and HT signal fields added to it, which results in increased overhead for PPDUs, which can cause performance degradation due to ACK frames compared to legacy format PPDUs

Abstract

The present invention relates to methods and apparatuses for transmitting and receiving legacy format data in a high throughput wireless network. A method of transmitting legacy format data in a high throughput wireless network, the method comprises accessing to the wireless network; receiving first data compliant with a first protocol, wherein the first data is transmitted by a first station accessed to the wireless network; and transmitting second data compliant with a second protocol to the first station, wherein the first protocol is downward compatible with the second protocol.

Description

[0001] This application is submitted to the China Intellectual Property Office with an application date of March 2, 2006, an application number of 200680000385.5, and an invention titled "Method and device for sending and receiving traditional format data in a high-throughput wireless network" Divisional application. technical field [0002] The present invention relates to wireless networks, and more particularly to methods and apparatus for transmitting and receiving legacy format data in high throughput wireless networks. Background technique [0003] Recently, due to the widespread use of the Internet by the public and the increase in the amount of available multimedia data, the demand for ultra-high-speed communication networks has increased. Since the emergence of local area networks (hereinafter referred to as LANs) in the late 1980s, the data transfer rate has significantly increased from about 1 Mbps to 100 Mbps. Therefore, high-speed Ethernet transmission is popul...
